NUT-LOCK.

SPECIFICATION formingpart of Letters Patent No. '756,145, dated-March29, 1904.

Application filed-December 6, 1902. Serial No. 134,220. (No model.) d

ing at Emlenton, inthe county of Venangoand State of Pennsylvania, haveinvented certain new and useful Improvements in Nut- Locks; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to nut-locks; and it relates particularly to thatclass of these devices Which are designed to prevent the turning of nutson bolts used for connecting the abutting ends of rails of steam andstreet railways. 4

The primary object of the present invention is to provide a nut-lock forthe purpose mentioned which shall be simple and cheap in construction,be capable of being quickly applied and removed, and whereby nuts onbolts applied to rail-joints may be securely held against turning.

With these objects in view the invention consists of the deviceconstructed and arranged substantially as hereinafter described,illustrated, and claimed.

The invention is illustrated in the accompanying drawings, in WhichFigure 1 is a perspective view of a rail-joint with my improvedlocking-plate applied thereto. Fig. 2 is a transverse vertical sectionalview on the line 00 m of Fig. 1. Fig. 3 is a perspective view of myimproved locking-plate; and Fig. 4 is a transverse sectional view of thelocking-plate, the section being taken on the line y y of Fig. 3.

In the drawings the numbers 1 1 represent, respectively, the meetingends of two rails of the universally-employed T shape, which rest uponand are secured to cross-ties 2 by spikes 3, passing through openings inthe edges of base-flanges of the rails and entering the crossties.

My device contemplates the use of the ordinary angle-bars 4: forconnecting the rails. These angle-bars are of a shape and size to restagainst the under sides of the treads 5 of adjacent rails, bear againstthe respective shanks 6, and to lie upon and parallel to the outerbase-flanges of'the rails.

Each rail is provided through its shank 6 near the end of the rail-withopenings, and the angle bars are provided with corresponding openingsfor the reception of bolts 8, having on their outer edges the nuts 9, bywhich the angle-bars are firmly attached to the rails. The purpose of myinvention is to prevent the loosening of these nuts 9 by jarringincident to the passage ofcars or trains over the rails or from othercauses. To this end I employ the lockingplates 10 of the peculiar andnovel form illustrated. The plates are composed of the outer portions11, having their flat lower faces 12 adapted to rest upon and be securedto the crossties,and the inner portions 18, adapted to rest upon thelower flanges of the angle-bars when the latter are in position on therails.

The outer portions 11 of the locking-plates have their upper facesinclined from their inner edges outward, and in the edges are a seriesof openings 14 for the reception of spikes having their heads resting onthe upper inclinedfaces 11 and entering the cross-ties in a manner toaid in holding the locking-plates securely in place. The'described formpresents a comparatively thin outer edge, so that the greater portion ofthe length of the spikes by which the plates are attached to the tiesmay enter the latter, affording a secure fastening. The inner portion ofeach of the locking-plateshas in its lower face an indentation of a formand size corresponding to the contour of the structures formed by theapplication of the lower flanges of the anglebars to the base-flanges ofthe rail ends. The outer ends of the indentations are formed by theabutments 15, against which bear the outer edges of the base-flanges ofthe rails and the outer edges of the angle-bars. The lockingbars areprovided with holes 16, the outer edges of which aresubstantially'parallel to the abutment, and these are adapted to receivespikes driven into the cross-ties. The inner edges of the spikes thusdriven enter openings in the edges of both the rail and of theanglebars, and thus when the spikes are firmly driven all the parts arefirmly held in place. The upper faces 17 of the inner portions of thelocking-plates are when the parts are in place substantially in ahorizontal plane, and the plates are so proportioned that when the nuts9 are turned to present flat lower faces the upper faces 17 of theplates will bear tightly against such lower faces of the nuts, and thusas the plates are firmly seated turning of the nuts from any cause isprevented.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination with the abutting ends of railwayrails, angle-platesapplied thereto, and bolts having nuts on their outer ends passingthrough the rails and plates, of a lockingplate having its outer portioninclined on its upper face and fiat on its lower face adapting it torest firmly on cross-ties, the outer edge being provided with openings,and having its inner portion formed on its lower face with anindentation tapering from its inner edge outward and of a size and shapeto receive the base-flanges of the rails and the lower flange of theangle-bars, and having its upper face plane to bear against the sides ofthe nuts, the outer edges of the base-flanges and of the lower portionsof the angle bars bearing against an abutment forming the outer face ofthe indentation, and openings through the plates adjacent to theabutments for the reception of spikes, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
